The metalis Couplings; and we do declare the 'followin caused 'to fill thecountersunk portion at the inner end of'the sleeve by the upsetting toolwhich flattens, the metal-in the countersunk part and at the same time afillet 5 is formed thus giving the sleeve and red at suitable finish 'atthis point: As the heated nu't'al contracts longitudinally the squaredeveled portions of'the rod are drawn imvardlwwith tremendous force,bringing the sleeve and rod into a 'union nearly as close as if theparts were integral. The protruding?en- ,larged end of the rod isthreaded, as at 6. Two opposite sides of the sleeve are flattened, as at7, to afford parallel surfaces to be engaged b'v a suitable wrench. S isa be; the axial bore of which is'threaded invention, such as will enableotli'ers skilled in the art ,to which it. appertains to nialre 'and usethe sanie, reference being bad to the accompanyingdrawings, .and',to theletters and figures 'of reference inarked thereon, which form a part ofthis specification.
